The unlikely pairing are collaborating on a new West End musical called Eugenius, which debuts at London's The Other Palace Theatre on Monday, January 22.

During an appearance on Good Morning Britain today (January 19), Ben revealed how the duo's union came about.

He said: "Myself and my co-writer decided we wanted to write a musical. We had certain people in mind to play some of the parts and there's a character in it called Evil Lord Hector, and we thought immediately of Warwick – I think that's because of some of his horror films that we watched growing up.

"So we thought, 'Wouldn't it be amazing if Warwick Davis could play this part?' We never thought that he would actually say yes. But he loved it so much that he didn't just play the part, he wanted to produce it as well. And that's how it all began."

Eugenius is set in the 1980s, and tells the tale of a teenage boy who wants to make a Hollywood comic book movie.

Ben added: "We grew up in the 1980s, so that's why it's so '80s inspired. We've been working on this for years. We just wanted to put everything we love about life and musicals into one big pot."

Star Wars and Harry Potter star Warwick was of course a teenager in the 1980s, and so is a huge fan of the production's music.
